• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the thermostat
sub-base. In dual transformer installations, the transformer common must come from the cooling transformer.
• For battery power, insert the 2 supplied “AA” type alkaline batteries into the battery compartment located in the rear
housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with
the +/- symbols in the battery compartment.
• If connecting this thermostat to a Wi-Fi network, a 24 VAC common (C wire) is required.
